It's the same freakin' game. ArmA 1 and 2 were made by the people who made OP:Flashpoint (it was published by Codemasters) How can this be much different?

Because OFP, ArmA and ArmA 2 were developed by Bohemia Interactive, and OFP 2 is being developed by Codemasters.
You can even tell from the trailers that both ArmA 2 and OFP 2 play out a lot differently from eachother.

The controls are pretty clunky and the game seems very unoptimized even though I was told it runs better than ArmA: Armed Assault, it doesn't.

No, it does. Well, on first release, it ran better than ARMA first release. It doesn't run better than an ARMA: Combat ops patched to 1.14 or higher though. Also, yeah, the controls can be clunky. You really need to get used to it. Anyway, I'm not getting this game. As soon as I saw the clip of "As you can see I've been shot in the head but it's nothing serious," I lost all faith.

No, BIS (Bohemia Interactive Studios, same people who made VBS 2) made ARMA and ARMA 2. The spirit of OFP went with them. As in, this does not look anything like OFP (and I don't mean graphically.) That doesn't mean that it'll be a bad game, but it just...isn't the same. The ARMA games would appear to be the closest predecessors to OFP so far- I'll be very happy if I'm proved wrong and OFP 2 is a great game despite the head shot thingy. Looking at the trailer, it reminds me of COD 4. I don't know why, it feels different, but it just...does. Maybe just the scenario.

And this guy that's rating everyone late, mus really have no life if he has nothing better to do than to go around facepunch rating everyone late.

True, but by saying that you gave him the atttention he wanted. Just ignore him.

Also, am I the only one that finds the music in the ArmA2 autorun very similar to the title theme of Donkey Kong Country 2? It's not the same I know that, but as soon as I heard it I was reminded of DKC2.

I suppose CM had the same choice Bethesda did with fallout.
Cater to the fans, piss off mainstream, or cater to mainstream and piss off fans.
The best way to avoid this would be just to call it Dragon Rising as opposed to OFP2

1337, it's realistic, not like arma 2 realistic but like red orchestra realistic, trust me it's not run and gun, the arcade mode will be but the regular won't.

Have you played it?
I mean I haven't but the E3 gameplay was also arcadey as shit.
I hate to use this quote again, but as one site said:
"Codemasters may have the OFP name, but Bohemia has the soul."
Bolded is the exact issue.
It's not Red Orchestra, it's a sequel to OFP. Keep it as realistic as OFP or drop the name.
